[email protected] 1. Introduction 1.1 SWT are spoken in Mainland SEA covering Northern Vietnam, Southern China, Laos, Thailand, Malaysia, Northern Myanmar, and the extreme east of India. 1.2 SWT languages belong to the Tai branch of the Kra-Dai family, formerly known as Tai-Kadai (see Ostapirat (2000) for discussion of the new term). 1.3 It is generally viewed as one of the three primary branches of Tai. 1.4 Various reconstructions of PSWT (Brown 1965; Jonsson 1991; Li 1977; Sarawit 1973) have been proposed but they differ in many important respects. 1.5 Some researchers (Chamberlain 1975; Luo 1997; Luo 2001) have expressed doubts on the validity of the SWT subgroup. 1.6 This paper: 1) shows that SWT is a valid genetic subgroup, 2) proposes a new reconstruction of PSWT, and 3) discusses some notable features of the proposed PSWT. 1.7 Data from 28 SWT dialects (see Appendix A) 2. SWT as a valid subgroup 2.1 Traditional view: Li (1960; 1977) and Haudricourt (1956) differ with regards to the relationship between SWT and CT but agree that SWT is a sub- branch of Tai. 1 SEALS XVIII (May 21-22, 2008) Universiti Kebangsaan Malaysia, Bangi Figure 1 Tai subgroup structure according to Li (1960; 1977) and Haudricourt (1956) PT PT NT CT SWT NT CT SWT Li (1977) Haudricourt (1956) 2.2 Chamberlain (1975): P/PH distinction 2.2.1 Reflexes of PT voiced stops *b-, *d-, *ɟ-,and *g- as criteria for grouping non-NT into two branches: P group ( p-, t-, c-, and k-) and PH group (ph-, th-, ch-, and kh-).
